Call of Duty: Black Ops 3 developer Treyarch looks set to make a big announcement later this week. The high profile reveal has been hyped by Call of Duty fans and broadcasters on social media.

In a tweet posted earlier this evening, Call of Duty YouTuber JCBackfire confirmed that Treyarch will be making some sort of “REVEAL” later this week. On Thursday, May 4 at 10AM PT, Jason Blundell, who was the game director for Call of Duty: Black Ops 3 will make an appearance on the JCBackfire channel to make said announcement. While JC unfortunately didn’t drop any hints at what the reveal may be specifically, the YouTuber did urge people to subscribe ahead of time, also saying that the Treyarch partnership is a “huge opportunity” that “literally means the absolute world.”

If rumors are to be believed then the YouTuber’s excitement is perfectly reasonable. Earlier this week it was leaked that an expansion DLC pack for Call of Duty Black Ops 3, called Black Ops 3 Chronicles, would go on sale this summer. This additional content to the 2015 shooter would introduce more maps to the massively popular Zombies mode, giving players even more locations to put the undead masses down once and for all.

With Treyarch having teased more Black Ops 3 DLC for 2017 and with leaks from retailers and ratings boards seemingly having confirmed that Zombies Chronicles exists, it seems unlikely that this big reveal will be for anything else. And if the expansion really is happening, hopefully the developer will take some time during this YouTube spectacula;r to address some vital questions.

For example, upcoming World War 2 shooter Call of Duty: WW2 has a Nazi Zombies multiplayer mode, making it clear that interest in Call of Duty zombie gameplay is at an all time high. But how with the Zombies Chronicles expansion avoid encroaching on WW2‘s turf? And what is the developer doing to make its rumored (for now) DLC a lot different to the Zombies mode in the new game?

These are important questions if only because it can help people figure out whether Call of Duty: WW2 is worth buying or not – as many players are likely to pick up the game based on the Nazi Zombies hype alone. People will also want to know whether or not Black Ops 3 will end up taking sales away from Call of Duty: WW2 as a result. For now, Treyarch hasn’t answered those questions but maybe the developer will have the answers later this week.

Call of Duty: Black Ops 3 is available now on PC, PS4, and Xbox One.
